This is a short tutorial to explain how to download several accessions. This is valid for both contigs or unitigs. In this example, we will download unitigs.
Prepare a text file of the list of accessions you wish to download. Say, accessions.txt containing:
DRR000273
DRR000280
DRR000294
DRR000300
DRR000305
DRR000339
To download the unitigs for all these accessions, a simple Bash command will do:
cat accessions.txt | xargs -I{} aws s3 cp s3://logan-pub/u/{}/{}.unitigs.fa.zst . --no-sign-request
